Suckers are freely produced in any light free soil.

P. PADUS (_syn Cerasus Padus_).--Bird Cherry or Hagberry. An indigenous
species, with oblong, doubly-serrated leaves, and terminal or axillary
racemes of pure-white flowers. It is a handsome and distinct
small-growing tree, and bears exposure at high altitudes in a

P. PANICULATA FLORE-PLENO (_syns Cerasus serrulata flore-pleno_ and _C.

Flowers double and white at first, but afterwards tinged with pink,

culture, there being white, rose, and crimson-flowering forms.

P. PUDDUM (_syns P. Pseudo-cerasus_ and _Cerasus
Pseudo-cerasus_).--Bastard Cherry. China, 1891. There are very few more

double-flowering Cherry. It makes a charming small-growing tree, is of
free growth and perfectly hardy, and one of, if not the most,
